Mix the beans. In a bowl, blend the refried beans and taco seasoning using an electric hand mixer. Set aside.
Assemble. To assemble the 7 layer taco dip, use a deep 9×13 dish or a deep glass trifle bowl. Begin spreading each layer, starting with the refried beans, sour cream mixture, guacamole, Pico de gallo, shredded cheddar, and a handful of sliced olives. I like to garnish mine with green onion or chopped cilantro. Cover and serve chilled.
